Which type of energy is defined as energy that flows due to a temperature difference?

Heat energy is the type of energy defined as energy that flows due to a temperature difference. This form of energy transfer occurs from a region of higher temperature to a region of lower temperature, and this process can take place through conduction, convection, or radiation.

In conduction, heat is transferred through direct contact between materials, while in convection, it involves the movement of fluids (liquids and gases). Radiation, on the other hand, allows heat to be transferred through electromagnetic waves, such as infrared radiation, which is why you can feel warmth from the sun even though space is a vacuum.

The concept of heat energy playing a crucial role is evident in various natural and industrial processes, such as in heating systems, cooking, and engine operations. Understanding heat energy is significant in fields like thermodynamics and engineering, where temperature variations are examined to optimize systems and improve energy efficiency.
